Abstract (en)
A method and apparatus are disclosed for accelerated detection of a data stream for embedded sequences of data bits referred to as "multi-byte sequences" in a data stream, used for high level interpretation or structuring of the data. The data stream is monitored continuously during normal data transfers between buffers along a data path for which several types of data may be transferred in interleaved fashion, without additional time used in the data transfer process. For data in which the special byte sequences are to be detected if present, the existence of data bytes associated with the special byte sequences is flagged, enabling byte-by-byte scanning to be skipped for those transfers in which no sequence is flagged. Special character sequences which begin in one data transfer and are completed in the following one are also indicated.
